Applications
Lockers by the row, not by the door.
Retail store cabinets and mall display cases get the same electronic lock — but EL21 is where locker rows, shelf runs and back-of-house blocks of cabinets are the whole job. No power supply and no drilling keep the conversion cheap per door.
Office lockers
Personal lockers stop running on keys that get lost, borrowed and laminated — staff unlock with the 2.4G smart key and the lock never needs a battery change.
Warehouse shelves
Picking stations and shelf stock get a lock that requires neither wiring nor a nearby socket — sealed off with the same body as the storefront.
School lockers
Locker blocks of 10, 30 or 100 doors stay manageable for whoever holds the smart key — no paddle locks, no record book.
FAQ
Answers before you ask.
How is EL21 different from EL20?
They are the same line of 2.4G sliding cabinet locks — same white body, ABS + zinc alloy + stainless steel, 63 × 38 × 32.5 mm, no power supply, no drilling. EL21 is the model to quote when the job is a run of lockers or shelves rather than one cabinet door.
What powers the lock?
Nothing to plug in: EL21 requires no power supply. Decoding happens over the 2.4G smart key, which is exactly why the lock can go on cabinets with no mains access.
Can existing lockers be converted?
Yes for typical units — installation is easy to install, use and maintain, with no drilling or tools required, so the lockers stay as they are while the locking changes.
How many lockers can one smart key handle?
Key configuration depends on the locker plan and is set up with the order — send us the locker count and layout and we will confirm the right configuration within 48 hours.
Why stop using physical keys?
Multiple physical keys are an inefficiency and a risk: copies get made, keys get lent, and nobody knows who opened what. The 2.4G smart key closes that loop for cabinet security.
